Title: Magnetic disk driver
Inventor: SAITOU ETSUROU
IPC: G11B23/033
Filed: 1983-06-20
Abstract: PURPOSE:To improve the stability for rotary driving of a magnetic disk by bearing a disk driving shaft within a shaft inserting slot and producing the twist to a pressure bar which gives the springy pressure to the positioning surface formed within said slot. CONSTITUTION:The inserting depth l1 into an inserting slot 14 of a rotary shaft 16 of a magnetic sheet S is set less than the thickness t1 of a center core 2, i.e., <=1/2 total height of a pressure bar 21. As a result, a twist is produced so that the bar 21 is tilted toward the center of the slot 14 at the side of an upper end 21B with both ends 21a and 21a of the bar 21 defined as fulcrums respectively. Thus the spring contact is reduced for the bar 21 owing to said twist. Therefore no shift is produced between the revolving center of the sheet S and the axial core of the shaft 16 even with the reduced attracting powe of a magnet 13 and the increased spring force of the bar 21. Thus the shaft 16 can be smoothly put into the slot 14. As a result, the loading state of the sheet S to a driving shaft 15 and the sheet S can be revolved with high stability.

Title: Paper feed apparatus of printer
Inventor: YOKOYAMA KOICHIRO
IPC: B65H20/02
Filed: 1990-04-24
Abstract: PURPOSE:To transfer overlapped long sheets of papers without shifting the papers by arranging driving rollers respectively pairing paper contacting members at the paper feeding side and paper discharging side in a crossing fashion at the side of a platen and at the side of a recording head. CONSTITUTION:A pair of paper feed rollers 1 has a driving roller 1a at the side of a printing head 6 and a follower roller 1b at the side of a platen 5. On the other hand, a pair of paper discharge rollers 3 has a driving roller 3a arranged in a manner to cross the platen 5. When a plurality of overlapped recording papers (s) are transferred onto the platen 5 by the pair of paper feed rollers 1, the recording papers facing the platen do not receive a large friction force and a compulsory transfer force, and therefore they are delayed than the papers facing the printing head, resulting in a slight displacement of the recording papers. However, the recording papers at the side of the platen are brought in touch with the driving roller 3a having a large friction force when they are completely recorded. Accordingly, since a compulsory transfer force works on the papers, the displacement of the recording papers can be solved.
